No, the correct answer is B. Physical change because the identity of the substance does not change.
For example, if you take a piece of paper and tear it in half you actually changed its property because now those pieces of paper have half the weight and and size that they did before you did anything. Now you know its a physical change because its still paper all you have done is change the physical appearance.

Answer:
C) philosophical and intuitive speculation
Explanation:
Hi
Leucippus and Democritus proposed the concept of an atom based on philosophical speculation as a way of explaining reality with the scarcity of data available at that time.
The ideas of Leucippus and Democritus were rejected at that time but later retaken by Dalton when proposing his atomic model.
Success with your homework.
Answer:
I’ll give you two possible conditions:
(1) An acid is present in an aqueous solution. The acid will donate a proton to the water to form hydronium. (That’s not really what happens, but that’s how we usually think of it.)
(2) The autoionization of water: in a pure water solution (or not a pure solution, doesn’t matter), one water molecule donates a proton to another water molecule, forming equal numbers of hydronium and hydroxide ions.
B. Unless you melt the solid the solid will hold its form
